Antibiotic-Producing Stetomyces


Book Description

The Bacteria: Volume IX: Antibiotic-Producing Streptomyces explores how Streptomyces, including actinomycetes, produce a variety of antibiotics such as aminocyclitols, ansamycins, macrolides, and tetracyclines. Topics covered range from physiology and fermentation to genetic recombination and chromosome mapping in Streptomyces, biomodification of antibiotics by Streptomyces, and biosynthesis of tylosin and erythromycin. The genome structure and evolution of Streptomyces are also discussed. This volume is comprised of 10 chapters and begins with a discussion on the taxonomy of Streptomyces based on morphology, physiological characteristics, the composition of cell constituents such as cell walls, and the presence of characteristic lipids, sugars, and quinones. The discussion then turns to the intraspecific and interspecific recombination in Streptomyces; pathways of DNA repair and mutagenesis in Streptomyces fradiae; strategies for isolation of improved Streptomyces mutants for antibiotic production; and derivation of DNA cloning vectors from Streptomyces phages. The biology and use of Streptomyces plasmids as cloning vectors are also described. The final chapter is devoted to major structural classes of antibiotics produced by Streptomyces, including anthracyclines and other quinones, ß-lactams, macrolides, nucleosides, peptides, polyenes, polyether antibiotics, and tetracyclines. This book will be of value to microbiologists, bacteriologists, biochemists, and biologists.

Genetics and Biochemistry of Antibiotic Production


Book Description

* Emphasizes the molecular genetics of antibiotic production * Provides the latest information on the organization of genes encoding the biosynthetic pathway * Explores the mechanisms governing their expression and regulation * Examines the role of resistance genes in protecting organisms from their own lethal products Genetics and Biochemistry of Antibiotic Production brings together the most up-to-date information on the genetic and biochemical mechanisms involved in antibiotic production. A collection of internationally recognized authors provide the latest information on the organization, function and regulation of genes responsible for antibiotic synthesis in a range of bacteria. This unique book groups antibiotics according to their biosynthetic affiliation, providing a background into evolutionary relationships while raising intriguing questions about the raison d'etre of antibiotics in nature.




Dictionary of Antibiotics and Related Substances


Book Description

Bacterial and parasitic diseases are the second leading cause of death worldwide, according to a report by the London School of Economics. Due to the emergence of drug-resistant "superbugs," like methicillin-resistant Staphylococcus aureus (MRSA), traditional antibiotics such as penicillin and its derivatives are in danger of becoming obsolete.

Recent Progress in the Chemical Synthesis of Antibiotics


Book Description

The use of antibiotics in the treatment by antibacterial and antifungal chemo therapy, has become standard practice since the end of World War Two and has had an enormous impact on healthcare throughout the world. Compounds belonging to this class have also reached an important place in the medical treatment of human cancer. Although, the discovery of most of these agents came from more or less sophisticated screening programs of soil microrganisms, many of the important antibiotics used today in clinical practice are derived from the original biosynthetic products by the application of often novel and generally elaborated chemical synthetic methodologies. In fact the antibiotics have represented (and still represent) for a generation of organic chemists an endless source of molecular structures whose varied assemblage of carbon atom backbones and chemical functions was beyond any possibility of imagination. Perhaps a similar repertoire of chemotypes was formerly offered by the natural products, namely the alkaloids, the terpenes, the vitamins and hormones as well as the pigments of the animal and plant kingdoms, albeit the chemical arrange ments of the antibiotic molecules appeared much more surprising and diverse to the admiring eyes of cultivated organic chemists. The idea of this book, certainly a landmark in the field, came during the Symposium of EUCHEM on Chemical Synthesis of Antibiotics, that was held at Aussois in Savoy, France (May 2-6, 1988), the initiative being taken by Gabor Lukacs to whom Masaji Ohno readily associated as a co-editor.
